Problems with Solid State Memory

Using solid state memory works great for many scenarios like consumer electronics, however being used as the primary drive in a computer is not one of them (yet). Each sector has a limited number of times it can be written to before it becomes bad (typically in the 1 to 10 mil range). If you are simply storing video or data files it will be a very long time before you wear this out.

When talking about scenarios where it is used to host an operating system, you have swap files which are repeatedly written to, applications that constantly create and destroy temporary files, cache data and delete it, etc. There are even write operations that occur simply with updating the last time a file was accessed not to mention full audit histories in some cases.

Before flash drives can become replacements the lifetime of the sectors needs to be increased dramatically, some sort of hybrid solution needs to be employed, or applications and operating systems need to be redesigned with those restrictions in place.
